To think that intelligence is our exclusive domain seems... well, not very intelligent.
I am very much concerned that when (not "if") AI arrives, the human race as a whole will not react well. Various pundits have talked about all the wonderful things AI could do for us, and I agree - those things and more will become possible. However, I believe that humans will react very poorly to becoming the second-class thinkers on the planet. Huge numbers of people participate in the mutual hallucination of religion, which to me signals that they are very, very, very insecure... that seems to me to be a recipe for disaster of several kinds.
What level of tolerance can we expect from a superior intelligence when we, as a race, exhibit intolerance of them? If, as seems likely to me, these intelligences obtain control over any means of power, we risk much by being irritants rather than reasonable cohabitors.
Even assuming that such intelligences tolerate that kind of stupidity, can we expect people to remain calm? After all, have we not witnessed immense fear, loathing, violence over imagined differences between very closely related intelligences (such as Negro / Caucasian conflicts)? And what little justification that there ever was for such acts seems to have been superficial or at the least socially based - speech, color, features - imagine a southern cracker or a Montana "Freeman" confronting something a couple of hundred times as smart as they are, and no possible way to deny it?
I think we have a real problem looming here.
